American like to visit the national parks. In 1996, over 250,000,000 people visited areas run by the National Park Service. Experts predict that by 2010, 500,000,000 people per year will visit the parks. As a result, people are trying to think of ways to protect the parks from the crowds.
The crowding of the parks has caused several problems. One is that there is not enough space for all of the people who want to use the parks. To cope with this problem, national parks may require reservations （预约）months in advance for some spots. The Park Service may also raise entrance fees at these places.
Another problem caused by increased park use is pollution. Some garbage and waste can be cleaned up, and the cleanup can be paid for by increased entrance fees. To cut down on noise pollution and air pollution, officials may decrease（减少） the number of cars allowed in parks. If this happens, people may use buses to travel around the parks. Officials may also limit（限制） the use of jet-skis, snowmobiles (摩托雪橇), motorboats, and sightseeing helicopters and planes.
The parks are also threatened by development that is going on around them. For example, around Yellow Stone Park, many motels (汽车旅馆), golf courses, resorts, and other tourist attractions have been built. Some of these developments affect areas that are used by animals. People will have to learn to agree about ways to protect the parks. If they do not, there will soon be no reason to visit these national treasures. By 2010, the number of visitors will rise by ______.
| A．250 million | B．500 million | C．2.5 billion | D．5 billion |
If you want to visit the national parks, you may have to _____ in the future.

| A．just for the benefit of the National Park Service |
| B．either to limit the number of visitors or to pay for the cleaner |
| C．not only to protect the animals but to reduce the noise pollution |
| D．merely for the development of the national parks |
What does the underlined sentence in the passage mean?
| A．People are not supposed to visit the national parks for fear that they will harm the animals. |
| B．Only if more man-made tourist attractions are built will more people visit the parks. |

A study has found, spending hours playing violent video games prevents teenagers from their moral growth. It is thought that regular touch to violence and lack of contact with the outside world makes it harder for them to tell right from wrong．They also struggle to trust other people，and see the world from their viewpoints．
Researchers from Brock University in Ontario found that those who spend more than three hours each day in front of the screen are particularly unlikely to have developed the ability to empathize(同情)．
The Canadian researchers surveyed 109 boys and girls，aged 13 and 14，about whether they played video games，which games they liked，and how long they spent playing them．Their findings found that 88 percent of teens said they played games，and more than half admitted to playing games every day．Violent games were among the most popular．
The teenagers also filled in a questionnaire designed to measure their moral development．For example，they were asked how important it is to save the life of a friend．
Previous studies have suggested that a person’s moral judgment goes through four phases as they grow from children and enter adulthood．By the age of 13 or 14，scientists claim young people should be entering the third stage，and be able to empathize with others and take their viewpoints into account．The research found that this stage appeared to be delayed in teenagers who regularly played violent video games．
It is also thought that teenagers who play games regularly did not spend enough time in the real world to learn to take others’ thoughts into consideration．Researcher Mirjana Bajovic said：“The present results indicate that some teenagers, who spent three or more hours a day playing violent video games，are deprived of such opportunities．” he added：“Touch to violence in video games may influence the development of moral reasoning because violence is not only presented as acceptable but is also justified and rewarded．”
They concluded that rather than trying to enforce an ‘unrealistic’ ban on the games，parents and teachers should encourage teenagers to do charity work and take up after-school activities．Why did the Canadian researchers carry out the studies?
| A．To develop teenagers’ ability to communicate. |
| B．To enrich teenagers’ awareness of social life． |
| C．To discuss how to save the life of a friend． |
| D．To measure teenagers’ moral development． |
What does Mirjana Bajovic want to tell us according to his words?
| A．Playing games regularly will improve teens’ intelligence. |
| B．Vio1ent games cost teens social experiences in real life． |
| C．Playing games makes teens help others. |
| D．Playing games inspires teens to develop fast. |
What would be the result of playing violent video games?
| A．Getting teens hard to take others into consideration. |
| B．Causing teens easier to tell right from wrong． |
| C．Helping teens make more good friends． |
| D．Making teens easy to get along with． |
What can be inferred from the text?
| A．Playing video games should be forbidden among teens. |
| B．Parents and teachers should let teens go online． |
| C．Teens should be encouraged to do more meaningful things. |
| D．Game designers should be kindly treated and rewarded. |
As the saying goes, man struggles upwards; water flows downwards. Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of “virtual water（虚拟水）”.
We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.
For example, consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310liters of the water—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East,get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.
In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products.The example of a sugary soft drink in Paragraph 3 is given to show_________.
| A．how drinks are shipped |
| B．how virtual water is exported |
| C．how virtual water is used |
| D．how drinks are made |
In which countries does most part of virtual water come from outside?________
| A．Kuwait and the Netherlands |
| B．China and the United Kingdom |
| C．America and the Netherlands |
| D．Israel and America |
What is the best title for the passage?
| A．Crops and Virtual Water |
